To closer understand the matter of the content, I have accessed a number of electronic versions of the book:
this s a complete digital version of one of the original prints of the book that shows original illustrations and typography, that I found quite interesting in terms of a primary research source.
Also I have accessed another version which is a more legible version to read, and is broken down into sections.
What I found interesting here that all sections vere numbered using geometrical formulas.
In order to see what has been done with the concept previously, I also watched a full feature film “Flatland” (2007) directed by Ladd Ehlinger Jr
and a short 30 minutye animation “Flatland: The Movie” made by Dano Johnson & Jeffrey Travis.
